5ks A/C oil charge?

[David]

If you are replacing the compressor, receiver/dryer and flushing the system, you've done more than 75% of the work to convert it to R134a. Why not just finish the job and do it with R134a? That way in the future, refills will be uber cheap. All you still need to do is replace the o-rings and the oriface tube or expansion valve (I think the 5000 has an oriface tube, but never BTDT).
